In the 1950s, a feral puppy is born, wondering what life's true purpose is. Two weeks later, he is whisked away to the dog pound and quickly euthanize, wondering if "fun" truly is life's purpose. His strong spirit is reborn and reincarnated as a newborn Retriever puppy in 1961. He leaves his cage at a puppy mill and is found by two garbage men who plan to sell him. They leave to drink, and the dog is spotted locked inside their pick-up truck by a young boy named Ethan and his mother, who rescue him from heatstroke. After they convince Ethan's father, the dog is allowed to stay and is renamed Bailey. Bailey and Ethan bond quickly, especially over the summer when the family visits Ethan's maternal grandparents' farm, and Bailey now believes Ethan alone is his purpose..
